1/13    The documentation of my Dell LCD is saying that the contrast
        button is not functional when the LCD is connecting with a DVI
        port. I assume you can still adjust it from the OS? How can I do
        it from Linux?
        \_ If you want to lower the brightness, you can achieve the same
           result by lowering the RGB value at the same time. That's what
           I did to achieve a comfortable viewing brightness for my Dell.
           Right now I am at 0% brightness, and RGB at 48%, the picture is
           really nice. Dell 2005fpw.
           \_ I got one of those 2005fpw's and I think I'll return it. The
              size wasn't as impressive as I thought so I want to wait for
              something better. But another thing was that if I turn out
              the lights and look at a black background, I can see uneven
              light leaking from the top edge. My LCD at work doesn't have
              any trace of that. Then again the 2005 is brighter. But it
              also has a weird viewing angle effect... even just sitting
              in front of it moving my head a bit I notice a purplish
              sheen at some angles. I won't buy another before seeing
              it in person. I hope they get OLED working well soon, that
              would be the proverbial shit.
              \_ purple tint, high viewing angles, good response rate?
                 Sounds like IPS tech!

                 I like my Samsung 193P from http://jr.com, but the 16ms MVA panel
                 used on the update of the Viewsonic VP191b at http://newegg.com
                 looks good too (you need models manufactured Dec 2004 or
                 later).  I have the 25ms VP191s and it ghosts, but nice
                 otherwise.
              \_ Hmmm, I have none of the problems. Maybe sample variation.
                 I am really pleased with mine, and I am very picky when it
                 comes to monitor calibration.
           \_ I have no problems with brightness since the brightness button
              does work. -op
              \_ So what do you need to adjust the contrast for? Be more
                 specific on what the problem is that you are trying to
                 solve...
              \_ I wish there were a button on my monitor to turn up the
                 intelligence.  There's a button called "brightness," but it
                 doesn't work.
